It most definitely helps!

I have been happily plugging away at my mission in the Foundry with the benefit of my notes and outline.

NemesisChiken suggests using a program called FreeMind in one of his tutorial videos on construction methodology. I highly recommend not only watching his video, but getting FreeMind to use for your outline.

It is a free program, and has helped me tremendously!

Good luck on your mission-building!
